lories; reduction of total fat usually lowers saturated fats. LDL changes are parallel to total serum cholesterol changes; HDL falls but is not parallel to total cholesterol (2:656S-657S).
Millen, Franz, Quatromoni, Gagnon, Sonnenberg, Ordovas, Wilson, Schaefer, and Cupples (1996) studied a sample of premenopausal and postmenopausal women to investigate relationships between diet and plasma total and LDL levels. Total cholesterol levels were found to be directly associated with total fat, oleic acid, and animal fat. Saturated fat was correlated with total and LDL cholesterol levels (657).
Polyunsaturated fatty acids are found to lower serum cholesterol. Research regarding effects of high polyunsaturated fat and low saturated fat intakes are mixed. This diet may result in harmful effect; some evidence shows that very high levels of polyunsaturated fats may increase gall stone formation. There is no clear evidence that intakes of over 10 percent of total calories from p
